IMPROVEMENT IN CHURNS.

Specification forming part of Letters Patent No. I 94,785, dated September 4, 1877; application filed June 18, 1877.

To all whom it may concern:

Be it known that I, EDWARD RHOADES, of Rockford, in the county of Winnebago and State of Illinois, have invented a new and useful Improvement in Ghurns; and I do hereby declare that the following is a full and exact description of the same, reference being had to the accompanying drawings and to the letters of reference marked thereon.

Figure l is a perspective view of the churn mounted upon trunnions within the support in g-frame, and Fig. 2 is atop view of thehead, showing the manner of securing the same to. prevent leaking while in operation.

Similar letters of reference denote corresponding parts in both figures.

The object of the inventionis to provide a simple and sure fastening of the removable head to that class of churns which revolve endwise; and it consists of the ordinary barrel-churn mounted in a frame of suflicient capacity to allow of an end-over-end revolution, and having an open head, made-by the use of a metallic ring, carrying perforated cars attached to the ring, into which. are simultaneously projected securing bolts or bars located upon the removable cover, and by means of which the cover is made fast to the churnbody, all of which will be hereinafter described.

In the drawings, A represents the churnbody; B, the uprights upon which the body is mounted; O, the foot-pieces of the frame; and G, the connecting cross-bar. D is a metallic ring, which can be tinned over or in any other manner made rust-pro0f, and upon which are secured upright perforated ears D. This ring is made to enter the groove cut in the end of the body, as is ordinarily done for securingthe head, and which, by having the hoops tightly driven upon the shell, keeps thewhole barrel in shape.

E is a metallic ring, supported by crucial arms E and to which is "secured a wooden arms f, by means of which the hub may be given apartial revolution, for a purpose hereinafter described.

F are bolts, pointed or made wedge-shaped at their outer ends, and having their inner" ends pivoted to the periphery of the hub F in such manner that as the said hub is turned to the right or left upon its central pivot a crank movement is given the bolts by the pivotal connection of the same with the hub, for the purpose of causing an end movement of the said boltswhen it is desired to lock or unlock the cover to or from the body.

13 are staples or guides, secured either to the crucial arms or to the rim of the cover, through which the bolts F slide, and secure the same from lateral displacement.

The ordinary packing may be used between the inner face of the cover and the metal ring forming the open head of the body.

If the churn is not evenly balanced by reason of the weight of the large quantity of metal used in forming its cover end, a metal countor-balance may be secured to the reverse or bottom end of the barrel.

The ordinary crank may be used for revolv- I ing the churn.

It will be observed that, in order that the point ed or wedge-shaped bolts shall press equally, the relative positions of the bolts and the securing-eyes must always be maintained, which could not be done were the eyes'secured to the wood portions of the body instead of to the I metal ring, as the moisture incident upon the use of the churn causes the wood to shrink and swell with the consequent variations in the positions of the fastenings.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a barrel-shaped churn-body having the open ring-head, the combination of the perforated ears located upon the open ring, the simultaneously-operating bolts entering the perforated ears, and the wooden cover incased in metal and resting upon the ring, all arranged and operating substantially as described.

2. The combination of the churn-body hav ing the open head, the cover having the sur- This specification signed and witnessed this rounding rim, and crucial arms carrying a 11th day of May, 1877. central hub, the wedge-sh aped bolts eccentrically pivoted vto the hub, the staples F and EDWARD RHOADES. the metallic ring having the vertical perforated cars, all these parts arranged and oper- Witnesses:
